Second, we need to ionize Br, which also costs energy, so it's +1140 kJ/mol. Third, we need to add an electron to K+, which releases energy, so it's -48 kJ/mol. Show more…

Calculate the standard free energy change for the reaction, $$ \mathrm{N}_{2(\mathrm{~g})}+3 \mathrm{H}_{2(\mathrm{~g})} \longrightarrow 2 \mathrm{NH}_{3(\mathrm{~g})} \text { at } 298 \mathrm{~K} $$ Given $\Delta H^{\circ}=-92.4 \mathrm{~kJ}$ and $\Delta S^{\circ}=-198.3 \mathrm{JK}^{-1} .$ Also, comment on the result.
Calculate the change in energy for the following processes: (a) $\operatorname{Mg}(g)+2 \mathrm{F}(g) \longrightarrow \mathrm{Mg}^{2+}(g)+2 \mathrm{F}^{-}(g)$ (b) $2 \mathrm{Al}(g)+3 \mathrm{O}(g) \longrightarrow 2 \mathrm{Al}^{3+}(g)+3 \mathrm{O}^{2-}(g)$ The electron affinity of $\mathrm{O}^{-}$ is $-844 \mathrm{kJ} / \mathrm{mol}$
Calculate the value of the energy change in aJ per ion pair for the reaction described by the equation $$ \mathrm{Na}(g)+\mathrm{H}(g) \rightarrow \mathrm{Na}^{+} \mathrm{H}^{-}(g) $$
